THC is fat-soluble. One common method of extracting THC for use in edibles is to immerse the marijuana in melted butter and then use the THC-infused butter to cook/prepare the edibles. I discovered this when I had bad complications after gallbladder removal - my pancreas got infected & necrotic. Eating too much fat would cause an acute attack of pancreatitis. For comparison, people who have had pancreatitis, kidney stones <i>and</i> given birth vaginally report that pancreatitis is the worst of the 3. By trial and error (namely repeated hospitalizations), I discovered that the maximum amount of fat I could tolerate at a meal was 7 grams of fat. This is about 1 pat of butter. Or half of a White Castle slider. Then, 12 hours later, I could safely eat the other half of the slider. I had gotten a medical marijuana card in Colorado by that time.<p>Milk contains fat, therefore the fat content of milk will be absorbing and extracting THC that enters the bloodstream of the cow.<p>For treatment of chronic pain after that surgery-gone-wrong, I have to get my pain meds from a pain clinic. At least 3 times per year, I have to take a urinalysis drug-screen to ensure that:<p>0. I'm taking my meds and not selling them, and<p>1. I'm not taking other drugs like THC, meth (my state's #1 illegal drug of choice!) or whatever is popular these days.<p>Anti-nausea meds like Zofran & Reglan metabolize into something that standard drug screens think is THC. I almost got kicked from the program because of this.<p>I bet that if I walked past a drug-sniffing police-dog that it would have either a seizure or an orgasm.
THC will be metabolized / broken down in the process, and the cannabinoids showing up in the milk and fats in the meat will be much further down the chain.
Anecdote:<p>Many moons ago in college, our neighbors kept a chicken coop and had roughly 10 chickens. Chickens are opportunistic feeders, and will eat nearly anything. Many people, mostly students, in our neighborhood smoked a fair amount of pot, and everyone would save their stems and regularly feed them to the chickens. We would routinely harvest their eggs, and more than once did we have (non smokers) who also harvested the eggs complain that they'd get headaches or feel drowsy after eating said eggs. Fascinating.
So what else is getting into milk that we don't know about yet? Pokeweed? Datura? Have people been randomly getting their consciousness altered by milk for centuries? That could explain a lot of history...
